AirTAC 2KSA Series: Stainless Steel Direct Acting Normally Open (NO) Valve
The AirTAC 2KSA Series (Direct Acting) is a specialized 2/2-way solenoid valve designed for high-temperature and steam applications where a zero-pressure startup is required. Constructed with a 304 Stainless Steel body and high-performance PTFE (Teflon) seals, it is engineered to withstand extreme thermal environments that would destroy standard valves.
As a Normally Open (NO) model, it allows flow when de-energized and closes only when the coil is powered. The direct-acting mechanism ensures that the valve functions reliably regardless of system pressure, making it perfect for low-pressure steam sterilization and specialized chemical dispensing.
Key Product Features
-
Zero-Pressure Functionality: Operates from 0 MPa (0 psi), allowing it to control steam or liquids in gravity-fed or vacuum-assisted systems.
-
High-Temperature Design: Specifically rated for steam up to 183°C and hot water or oil up to 150°C.
-
Normally Open (NO) Security: Ideal for cooling loops or pressure-relief lines that must remain open during a power failure to ensure equipment safety.
-
SUS304 Stainless Steel Construction: Provides the highest level of durability against corrosion, rust, and thermal stress.
-
PTFE (Teflon) Seals: Offers universal chemical compatibility and maintains seal integrity under high heat without becoming "sticky."
